Standard Test Methods for Bend Testing of Metallic Flat Materials for Spring Applications Involving Static Loading
|Publication Date:||1 January 2000|
1.1 This standard describes three test methods for determining the modulus of elasticity in bending and the bending strength of metallic strips or sheets intended for the use in flat springs:
1.1.1 Test Method A--a cantilever beam,
1.1.2 Test Method B--a three-point loaded beam (that is, a beam resting on two supports and centrally loaded), and
1.1.3 Test Method Ca four-point loaded beam (that is, a beam resting on two supports and loaded at two points equally spaced from each support).
1.2 Values stated in inch-pound units are to be regarded as the standard. SI units are provided for information only.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
